Days to Sprout: 7 – 12 days
Matures In: 30 – 40 days
Prune a few stems when you remove the wilted flowers as they bloom. These cuts will encourage the development of new branches, which will bring new flowers. The cut should be made at one-third to one-half the height of the stem.
If your petunias get more overgrown than you prefer, you can cut them back.
